Higher implantation and live birth rates with laser zona pellucida breaching than thinning in single frozen-thawed blastocyst transfer

While zona pellucida (ZP) breaching of day-3 frozen blastocysts embryos can increase the blastocyst hatching rate, compared with ZP thinning, the pregnancy and implantation rates are similar. The aim of this study was to compare pregnancy outcomes and the risks associated with frozen–thawed blastocy...
